Definitions
- Structural component with a plurality of organo pieces and method for its
- the present invention relates to a structural component according to claim 1 and to a method for producing a structural component according to claim 9.
- Structural components can be used, in particular in the automotive sector, e.g. have a supporting and / or structuring function.
- the possible locations are diverse; Examples include parts of seat frames, doors and the body.
- Suitable matrix materials are, for example, polyolefins, in particular polypropylene, and also plexiglass, polycarbonate, polystyrene and / or polyamide.
- the thermoplastic matrix can melt, whereby a material-locking connection with the molded Page 2
- organo sheets are extremely versatile materials with which it is possible to produce structural components of low weight with high stability.
- the Applicant is internally known from practice to produce structural components of several organo pieces. So that the individual organoblech pieces are securely fastened together in the finished structural component, the organoblech pieces are usually placed together with a relatively large overlap and hot pressed. So that the organoblech pieces hold together securely, it is necessary to provide comparatively large overlap areas. For the stability of the structural component, however, such large overlap areas are often unnecessary. Since the production of organic sheet is very expensive, but its efficient use of the structural component is desirable. In addition, it has been shown that the hot pressing of the organoblech Publishede must take place within a relatively small optimal temperature window. The exact monitoring of the temperature can thus make the production process comparatively expensive.
- Object of the present invention is to provide a structural component that allows the most efficient use of organic sheet.
- Such a structural component in particular for a motor vehicle, comprises two or more organo-plastic pieces which, at least in sections, lie over one another, in particular flat against one another.
- the organoblech pieces each have a fiber layer.
- At least in the fiber layers of the Organoblech publishede a pair or a plurality of pairs of mutually aligned holes are formed on (and by) which the Organoblech disturbede are attached to each other, at least by a positive connection, in particular by a positive connection of the Organoblech dividede each other.
- the one hole of a pair of aligned holes is formed on the one organic sheet, while the other hole of the pair is formed on the other sheet of organic sheet.
- the two or more organoblech dividede (which can also be referred to as organo-patches) can be attached to each other particularly safe and with a very small overlap.
- Organoblech mixturee to the aligned (eg in coincidence Page 3) holes allows a particularly secure attachment of Organoblech published each other.
- the attachment of the Organoblech thoroughlye each other is carried out in particular in the form of a permanent connection. For example, a portion of the one organoblech piece engages the other organoblech piece on the hole formed therein.
- the individual organoblech pieces can e.g. each be designed as an organic sheet blank, for example, be cut or punched out of a larger sheet of organic sheet.
- organo sheet blanks it is desirable to produce a small blend to achieve the most efficient use of organo sheet.
- the proposed structural component makes it possible to provide even smaller pieces of organic sheet, which would previously have been lost as waste in the structural component.
- the proposed structural component enables more heavily stressed areas of the structural component, e.g. with a more resilient (e.g., thicker and / or thicker fibrous) organo-sheet, especially if those areas are comparatively small. This also makes a particularly efficient use of organic sheet is possible.
- the Organoblech concentratede may be continuous fiber reinforced Organoblechquoe.
- continuous fiber reinforced means that the length of the reinforcing fibers is essentially limited by the size of the sheet-shaped pieces of organo-sheet (at least prior to a forming process). It can thus be provided that a fiber is essentially not interrupted within the edges of the continuous fiber-reinforced organic sheet piece.
- the positive connection may in particular be formed between the fiber layers of the organoblech pieces.
- an organic sheet with its fiber layer for example, with an edge of the hole, extends into the hole in the other Organoblech Gla, so as to establish a positive connection.
- the fiber layers in the region of the aligned holes can be at least partially pushed into each other or mixed, so that there is a positive connection between individual fibers.
- a filling may extend through the at least one pair of aligned holes.
- the filling can be materially bonded to the thermoplastic matrix of one or both organic sheet pieces (and thus produce a material-locking connection between the pieces of organic sheet).
- the filling allows a particularly secure connection of Organoblech Federatione.
- the filling may for example consist of an injection molding material, in particular a fiber-reinforced (for example long glass fiber reinforced) injection molding material.
- the organoblech pieces can be sewn together by means of injection molding material.
- the filling comprises e.g. the same material or consists of the same material as the matrix of at least one of the organoblech Publishede.
- it may comprise the same material as the matrix and be additionally reinforced with fibers.
- the filling extends in particular through the pair (or pairs) of the aligned holes.
- the filling can be formed in one piece (in particular of the same material), each with a holding part.
- the holding parts each have a larger diameter than the aligned holes. In this way, a particularly secure positive connection of the Organoblech publishede is possible.
- a plurality of pairs of aligned holes are provided, each formed at least in the fiber layers of the organic sheet pieces. For example, more than five, more than ten or more than 20 pairs of aligned holes are provided. As a result, a particularly secure attachment of Organoblech Publishede each other even on a small overlap area is possible. In addition, then the individual holes can be formed with a small diameter.
- a reinforcing rib may be formed between at least two pairs of mutually aligned holes, which are each introduced at least in the fiber layers of the overlapping organo-body pieces.
- the reinforcing rib extends along at least one of the organo-plastic pieces from the one pair to the other pair.
- the reinforcing rib may in particular be integral with page 5
- Fillings of the at least two pairs of mutually aligned holes may be formed.
- the fillings can be secured in their position.
- the holes provide a particularly secure (e.g., unitary) attachment location of the reinforcing rib.
- each at least one reinforcing rib may be formed on either side of the superimposed Organoblech Federatione each at least one reinforcing rib.
- the reinforcing ribs may e.g. be integrally connected (in particular the same material) over the fillings of the pairs of aligned holes.
- Providing two or more pieces of organic sheet, particularly in the form of organic sheet blanks may include cutting an organo sheet to form one or more of the organo pieces);
- the formation of the positive connection of the organo-plastic pieces may be a consequence of the introduction of the through-hole, e.g. in that material sections of both organic sheet pieces are brought into engagement with one another by piercing.
- the steps of arranging the organic sheet pieces, inserting the through hole and fixing the organo sheet pieces to each other can be performed in the same tool, particularly in an injection molding tool.
- the organoblech Irishe Before or after the introduction of the through hole, the organoblech Irishe can be reshaped.
- the organoblech pieces are heated prior to insertion into the injection mold or in the injection mold and formed during closing of the injection mold.
- the organic sheet pieces can also be pressed together, which allows an additional areal adhesion to one another.
- the at least one through hole extending through the two organic sheets may be introduced in a heated state of the organic sheets.
- the matrix of each of the organoblech pieces is plastically deformable.
- the through-hole is made by means of at least one mandrel, e.g. in the form of a needle, (jointly) introduced into the (superimposed) Organoblechstede.
- the mandrel may be attached to the injection molding tool.
- By piercing the mandrel in the previously heated Organoblech publishede it is possible to introduce a hole without severing the fibers.
- the fibers of the fiber layers of the organic sheet pieces may be pushed aside.
- the fiber layers can interlock and / or positively engage behind.
- the Organoblechstede can thus be needled together.
- an injection molding material is injected onto the organic sheet pieces (in the injection molding tool), wherein the at least one through hole extending through the organic sheet pieces is filled with a filling of injection molding material and / or reinforcing ribs or other functional elements are injection-molded.
- the reinforcing ribs and the filling can be injection-molded onto the organic sheets as a continuous injection molding section. Page 7
- At least two, in particular more, each extending through the organoblech pieces through holes are introduced into the Organoblech publishede, which allows a particularly secure attachment.
- At least one reinforcing rib can be injection-molded onto the organic sheet pieces such that it connects the at least two through-holes (and in particular the fillings introduced therein).
- the method may be designed, in particular, for producing a structural component according to any embodiment described herein.

- the organic sheet pieces 10A, 10B are thus punctured or perforated (in particular jointly).
- the holes 101 of the two organo-pieces 10A, 10B are aligned coaxially with each other.
- the holes 101 are in coincidence with each other, so they are aligned with each other. Together, the holes form a through-hole DL through both organo-pieces 10A, 10B.
- the piercing of the organoblech pieces 10A, 10B can in particular take place after a heating of the organoblech pieces 10A, 10B.
- fibers of the fiber layers 100 of the organic sheet pieces 10A, 10B have been pushed aside by the tip 20 of the mandrel 2.

- stiffening ribs 11 can be formed (injection-molded) on both sides of the interconnected organo-sheet pieces 10A, 10B, which can further increase the stability of the structural component 1 '.
- Injection of the organic sheets 10A, 10B through the needled through-holes DL may also be referred to as "spray-sewing". Because it has a similar effect as sewing, e.g. by means of a thread.
- the injection molding material injected through the through-holes DL extends through the through-holes DL uniformly throughout the material and, through the stiffening ribs 11, over a plurality of through-holes DL.
- a particularly secure connection of the two organo-body pieces 10A, 10B is achieved.
- the organoblech pieces 10A, 10B are fastened to each other particularly securely, the overlapping area UB can be made comparatively small. In this way not inconsiderable amounts of organic sheet can be saved in addition to an improved, needs-based adjustment of the stability of the structural component 1 'with the lowest possible weight possible.
- the organo-sheet pieces 10A, 10B are hot-pressed (e.g., simultaneously with the spray-stitching) (particularly in a molten state) to achieve even further attachment of the organo-sheet pieces 10A, 10B to each other.
- FIGS. 1A to 2D each show the connection of two organic sheet pieces 10A, 10B.
- FIG. 3 shows a further exemplary embodiment of a plurality of organic sheet pieces, here three organic sheet pieces 10C-10E. page 12
- the Organoblech dealte 10C-10E are already preformed in FIG. 3, i. made by forming (in particular thermoforming) from a respective planar Organoblech Contest.
- the Organoblech institutionse 10C-10E are adapted to form together a structural component 1 "in the form of a part of a door inner panel of a motor vehicle.
- the organo-pieces 10C-10E have different properties from each other.
- the individual pieces of organic sheet 10C-10E are in this case adapted to the requirements of the structural component 1 "on that region which is formed by the respective organo-sheet piece 10C-10E.
- a first piece of organo-plastic sheet 10C forms in the finished structural component 1 "a flat portion, e.g. a part of an aggregate support, and is made of a (thin) organo sheet, in this case with a thickness of 0.6 mm.
- a second organoblech piece 10D forms in the finished structural component 1 "a part of a horizontal support of the door inner panel.
- the second Organoblech Sharing 10D made of a medium-strength organic sheet, in this case with a thickness of 1, 0 mm.
- a third Organoblech Sharing 10E forms in the finished structural component 1 "a part of a spar of the inner door panel.
- the spar has to withstand particularly heavy loads. Therefore, the first organo-sheet 10C is made of a strong organo-sheet, in the present example, 1.5 mm thick
- Figs. 4A and 4B show the organic sheets 10C-10E in a state of being superimposed.
- the first Organoblech Kab 10C and the (smaller) second Organoblech Kab 10D overlap over the entire surface of the second Organoblech proceedingss 10D.
- the second organo-sheet piece 10D thus reinforces the first organo-sheet piece 10C.
- the first organo sheet piece 10C and the (smaller) third organo sheet piece 10E partly overlap.
- the second and third organo-pieces 10D, 10E do not overlap.
- FIGS. 5A to 5D show the finished structural component 1 ".
- the three organo-pieces 10C-10E are attached to each other by spraying.
- a plurality of through-holes DL connect the first to the second organic sheet 10C, 10D and the first to the third organic sheet 10C, 10E.
- a network of stiffening ribs 1 1 is formed on both sides of the structural component 1 ". Page 13
- the edges of the organo pieces 10C-10E are molded with injection molding material. As a result, the fiber layers of the Organoblech Publishede 10C-10E can be protected. Optional eyelets or other connecting elements are molded onto the structural component 1 ". All molded sections can be formed without undercuts, which allows easy production.
- FIGS. 6A and 6B show a door inner panel 3 for a vehicle door, the structural component 1 "according to FIGS. 5A-5D forming part of the inner door panel 3.
- the structural component provides a structuring function (and in the example shown also a supporting function).
- FIGS. 6A and 6B show a structuring function (and in the example shown also a supporting function).
- the structural component 1 " is connected to a metal sheet, for example screwed, which forms the remaining inner door panel 3.
- the remaining parts of the door inner panel 3 are made in the form of a structural assembly as described herein.
- the illustrated construction of the structural assembly 1 "according to FIGS. 5A-5D is only an example.
- the structural assembly could form the entire inner door panel.
- a variety of organo pieces can be joined together by spray-sewing.
